Credit Rating - Short-term Rating

Short-term Rating

A short-term rating is a probability factor of an individual going into default within a year. This is in contrast to long-term rating which is evaluated over a long timeframe. In the past institutional investors preferred to consider long-term ratings. Nowadays, short-term ratings are commonly used.

First, the Basel II agreement requires banks to report their one-year probability if they applied internal-ratings-based approach for capital requirements. Second, many institutional investors can easily manage their credit/bond portfolios with derivatives on monthly or quarterly basis. Therefore, some rating agencies simply report short-term ratings.
